About the instructor

Hi, I'm Hakan Karsilar. I built this site because I believe statistics doesn't have to be intimidating. With the right visualizations and a bit of hands-on practice, anyone can build real intuition for how data works.

Every section is designed from the ground up — no hand-waving, no "just trust the formula." You'll see each concept in action, work through real examples, and test yourself along the way.
